Specific embodiment
Embodiments of the invention are described in detail below：
As shown in Figures 3 to 6, a kind of rotary drum pulping machine, including barrel tumbler body 10 and feed hopper 20, barrel tumbler body 10 are provided with
Charging aperture 11, feed hopper 20 is arranged at the charging aperture 11, and the feeding-passage 21 of feed hopper 20 leads to described charging aperture 11,
It is tightly connected by labyrinth seal structure realization between described barrel tumbler body 10 and described feed hopper 20.
Wherein, above-mentioned labyrinth seal structure includes seal ring seat 30 and an annular double wedge 40, and seal ring seat 30 is led to
Cross bolt to be connected with above-mentioned feed hopper 20, annular double wedge 40 is arranged on above-mentioned barrel tumbler body 10, and seal ring seat 30
Set around the central axis of above-mentioned charging aperture 11 with annular double wedge 40.The seal ring seat 30 is provided with one with annular double wedge 40
The closure gasket groove 31 being engaged, has in the embedding sealing annular groove 31 of annular double wedge 40, and between annular double wedge 40 and closure gasket groove 31
